You should REALLY play Phantasy Star. If you have a PSP, just buy Phantasy Star Portable 2.
It is an EXTREMELY good game.
Like, EXTREMELY good. It's a fighting game mixed with RPG like elements. And the Multiplayer, Dear god, the multiplayer is amazing.
I teamed up with a Level 200 and a Level 5 to defeat the evil dimension boss whose name I can't remember. The Level 200 crapped out on us, and me (level 15) and the level 5 (Then level 10) had to fight the most powerful boss by ourselves. And we beat it. It was tough, and the level 5 died alot, (but I revived him) and we beat it together with no hacker help.
